my OS is ArchLinux running on an old ASUS laptop. Recently, I picked a DVD box-set from the store and later realized that they just won't play in my computer. Thinking that the DVD's were faulty I went back to the store and to my surprise they worked quite well when played on the stores dvd-player.

I don't remember playing a DVD in the last few years but I did have a bunch of issues with region specific DVD's, this was quite a while back.

Usually, DVDs' are automatically mounted by Nautilus. I tried mounting the device with mount:

localhost% sudo mount -t iso9660 /dev/sr0 ~/cdrom 
mount: /dev/sr0 is write-protected, mounting read-only
mount: no medium found on /dev/sr0

I think the problem might very well be hardware related but any pointers would be more than welcome.

Output of the cd-drive command at paste-bin.

Update #1:

Here are the dvd* packages present in my OS:

extra/libdvdcss 1.2.13-3 [installed]
  Portable abstraction library for DVD decryption
extra/libdvdnav 4.2.0-2 [installed]
  The library for xine-dvdnav plugin.
extra/libdvdread 4.2.0-1 [installed]
   Provides a simple foundation for reading DVD video disks

Output of the cd-info command:

Disc mode is listed as: Error in getting information
++ WARN: error in ioctl CDROMREADTOCHDR: No medium found
cd-info: Can't get first track number. I give up

I should have checked the system logs. Here is what I found from journalctl when I tried playing the disc using vlc:

These are media DVDs or data DVDs? You typically don't mount media DVDs that contain movies and such. Also if this is a media DVD that contains movies and/or TV shows you'll likely need to install libdvd4 software so that your system can handle the encrypted content on the DVD.

See my answer to this question, titled: Can't play DVDs on Linux Ubuntu laptop.

cd-info

You can use this command, cd-info --dvd, to get more information about the installed DVD media. Here I have the Curious George DVD installed in my laptop.

Exmaple

$ cd-info --dvd
cd-info version 0.82 x86_64-redhat-linux-gnu

thanks for the quick response, I have noticed that I have the packages required for dvd-playback on my system, so I don't think thats the problem. –  feverDream Nov 5 '13 at 9:37
    
@feverDream - try the command lsdvd. –  slm Nov 5 '13 at 9:46
    
it says it can't find the device /dev/dvd –  feverDream Nov 5 '13 at 9:48
    
@feverDream - cd-info or cd-drive show anything? –  slm Nov 5 '13 at 9:49

I haven't tried cd-info and I have the output of cd-drive posted in the question via pastebin –  feverDream Nov 5 '13 at 9:51
